In Fig. l l'heve illustrnteg e. portion of e hethtuh 10 of ususl construction placed sgeinst as well 11 for conservation of spsce es is the usual procedure. Between the upright well of the bathtub 10 and the wall llextends the overflow pipe 12 while underneath the floor of the bathtub 10 extends the waste pipe 13. e The waste ipe '13 connects h means of an ehlow 14 andh v ing in the'hottoni of the bathtub in'the usual manner.

The usual T connection 16 communicates through the waste pipe 1?. connection 16 also carries a cylindrical valve 18 open at both ends and cooperating with the seat 19 and'the side walls of the upper portion of the 45 connection 16 to cut oil the flow of water between pipes 13 and 17 while allowing overflow from the pipe 12 into the pipe 17. A chain 20 connects the valve '18 with the valve controlling means mounted at the-upper and so of the overflow pipe 12. p

with the pipes 12 and 13 and afiords an escape- The upper end of the overflow pipe 12 is connected in covering relation to on evening si in the hothtuh is 5 means cl ow es gasket 23. The elhcrv' 22 is provided with legs 24: having threaded portions 25 {55 adopted to receive screws 26.. An escntcheon plate 2'? is adapted to engsge the opposite side of the hethtul) l0 and is provided e pair of openings 26 adopted to receive screws 26 Wherehp to clamp the elhoiv-22 and. gnslret '23 in sealing relation over. the opening 21.

The escntch'eon piste 2? Iney he provided with. openings to permitthe water to pass throiigh the opening 21 hot is preferably provided with an interrupted flange es indicsted st 28 which s eces Smld plate from the well. 1% whereby to e low the passage oi weterthereunder into the pipe 1 Y V The escutcheon 2'? is provided with so pair of porollel spe'ced propections 2t esch io of which has n louhle beveled endportion as indicated st 30. The pleie 2? is provided with an opening extending therethrough end positioned between the progiections 29. This opening comprises e pert-spherical socket 31 is sdjmcent the front of the pie. 2?" and e flaring portion 32 extending hccirwsrdly irom the socket 231. Above and below the projecr I tions 2% are cylindrical openings adapted to receive push buttons hereineiter descriheol. Eniending through the openinghe tween the projections 29 is s valve control bolt 34 provided with a; spherical head 35 adapted to seat in the socket, 31'. ihe bolt .34 is threeded as shown at 36 and provided 35 with a nut 33?. Loosely received on the bolt 34' is an overcentering plate 38 provided with parallel projections 39 at the two sides thereof. A spring 40 is compressed between the nut 3'2 and the plate 38. A projection 41 on the bolt 34 provides means for a connection'to the member 42 into which 'is threaded the uppermost link of the chain member 20. Extending through the openings 33 are push 95 buttons 43 provided with extensions 44 adapted to extend between the projections 39 and provided with cross pins 45 adapted to enga the rear surface of the propections 39. She date 46 on the buttons 43 are adapted tance from the center of rotation of the bolt 34 in the socket 331 to the two beveled faces of the projections 29 is less than the distance from such center to the point of intersection ofsuch faces. It follows that the bolt 34 and mechanism carried' thereby will be in stable e uilibrium when the bolt axis is perpendicu arto one of the beveled faces. Pressure on the buttons 43 will tend to rotate the overcentering plate 38 about the point of intersection of the beveled faces of the projection 29 and will also tend to rotate the bolt 34 and mechanism carried thereby in the socket 31. These provide tendencies to produce a control which can be snapped to its positions of stable equilibrium with remarkable little exertion while aiiording very considerable valve operating force. With themechanism illustrated it is possible to provide a spring of quiteconsiderable strength without causing the operation to require undue exertion.

From the foregoing it will be evident that I have provided a fixture for bathtubs which is well adapted for its intended purpose. While I have shown the preferred embodiment, I wish it understood that I am not limited to the details thereof except in accordance with the scope of the appended claims and the prior art;
